This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject Webling forms and memberlists with arbitrary web scripts that will execute whenever an administrator views the related form or memberlist area of the WordPress admin.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/webling/tags/3.9.0/src/admin/actions/save_form.php#L2","https://plugins.trac.wordpress.org/browser/webling/tags/3.9.0/src/admin/actions/save_memberlist.php#L2","https://plugins.trac.wordpress.org/browser/webling/tags/3.9.0/src/admin/lists/Form_List.php#L122","https://plugins.trac.wordpress.org/browser/webling/tags/3.9.0/src/admin/lists/Memberlist_List.php#L115","https://plugins.trac.wordpress.org/changeset?old_path=%2Fwebling/tags/3.9.0&new_path=%2Fwebling/tags/3.9.1"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-1263","score":0.00277,"percentile":0.20171,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
